oedals and do 7 Having now described the mechanism whereby elevating thepedals automatically closes the door 3', it remains to describe themechanism by which the door is interconnected with the door 3 tosimultaneously close said door also, in fact to cause the simultaneousoperation of said doors whether in closing or opening. This mechanismcomprises apair of pulleys 20 shown on the upper door-guide and locatedrespectively toward the rear end of the doors 5 and 3* when in closedposition. Cords 21 ant. 22 are looped about the pulleys 20 with the freeends of each cord connected one end to each door near its front edge.The shown arrangement of cords and pulleys comprises what amounts toacrossed-belt, made up of v the cords working on pulleys 20, each ply ofsaid belt being connected with oneof the doors 3 and 3 The result of theconstruction is that moving either door in either direction, opening orclosing, creates a'pull in the given direction on the ply of one of thecords, which pull is converted due to the pulley 20 over which said cordpasses into a pull in the opposite direction on the other ply of thesame cord, which being attached to the opposite door moves said door inthe opposite direction from that in which the first named door happensto be moving. Thus opening the door 3 moves 3 in the opposite direction,that is to say, opens it also, similarly closing the door 8 likewisecloses 3 The same thing is obviously true if the door 3 is the one whichis primarily actuated by the operator, Accordingly when as heretoforeexplained the handle 15 is operated to elevate the pedals and tosimultaneously close the door 3' through the cord 15, it follows that itwill at the same time cause the closing of the door 3 Obviously thepresent improvements are of great convenience to the users of pianoiplayers, since it makes it possible to close the pedals and tracker-boxdoors in one operation, whereas heretofore two independent operationshave been necessary? lvloreover both actions are veilected from a handle15 within convenient reach of the operator and requiring nosteeping.

It may he said hy. way of further explanation that 25 is a'screw-eyeprojecting from a. suitable support and receiving through it the cord16, said cord having a button 26 adapted to contact with the screw-eyewhen the spring 19' takes up on the cord to keep it tautcn the pulley.

Having thus described my in vention, what ll claim is:

1. In an automatic player, the combination of pedals; a pedal-elevatingmember acting to elevate the pedals by the operation of the member; asliding tracker-cox door; and cord and pulley means consisting of apulley-guided cord-connecting the door and the pedal-elevating memberand operating to actuate the door in cloning direction from theoperation of said pedal-elevating member.

2. In an automatic player, the combination of pedals, pedal operatingmechanism comprising a member adapted to he operated to elevate thepedals, tracke -hot; doors having an interconnection from the closingand opening'of either door to correspondingly operate the other door;and a cord and pulleyconnection between one of said doors and the memberwhich elevates the pedals, adapted from the operation of said member tomove said door from open to closed position.

3. In an automatic player, the combination of pedals, pedal operatingmechanism comprising amember adapted to be operated to elevate thepedals, tracker-box doors having an interconnection adapted from theclosing and opening of either door to correspondingly operate the otherdoor; a cord and pulley connection between one of said doors and themember which elevates the pedals, adapted from the operation of saidmember to move said door from open to closed position; and cordtightening means comprising an elastic connection with said cord,adapted to keep it at all times taut tion of movable parts; ;cord andpulley means consisting of a pulley-guided cord connecting the movableparts to operate one of them from the movement of the othe"; andcord-tighteningmeans consisting of an elastic connection, between theframe of the player and the cord, taking theredf at the pulley. i

In witness whereof, l haygsigned my name to the foregoing specificationin' the presence of two subscribing witnesses.
